Enhance i386_set_ldt to allow application to dynamic allocate
or free a LDT entry. The function has following prototype:
  int i386_set_ldt(int start_sel, union descriptor *descs, int num_sels);

Added Features:
o If start_sel is 0, num_sels is 1 and the descriptor pointed to by descs
  is legal, then i386_set_ldt() will allocate a descriptor and return its
  selector numbe

o If num_descs is 1, start_sels is valid, and descs is NULL, then
  i386_set_ldt() will free that descriptor (making it available to be real-
  located again later).

o If num_descs is 0, start_sels is 0 and descs is NULL then, as a special
  case, i386_set_ldt() will free all descriptors.
